Title: A method of and a device for regulating the height of a column of carbon black
IPC: G01F23/24
Filed: 1965-04-15
Abstract: 1,101,933. Automatic control of fluent level. CHEMISCHE WERKE HœLS A.G. April 15, 1965 [April 16, 1964], No.16192/65. Heading G3R. The height of a column of carbon black above an electrode located wholly in the carbon black is determined by the electrical conductivity of the carbon black between the electrode and an adjacent electrode making contact with the carbon black. As described, carbon black is continuously produced and transferred to a hopper. A strip electrode is located well below the level it is desired to maintain in the hopper, and variations in conductivity between the electrode and the casing, or insulated electrode holder, serve to control, through a servosystem, the opening of a pneumatically operated cylindrical valve beneath the hopper and thus the rate of pneumatic extraction from the hopper so that the level in the hopper is maintained constant. A rotary paddle may be located just above the valve to prevent clogging. Warning signals are produced if conductivity should rise or fall to predetermined value corresponding to maximum or minimum levels. A further valve in the outlet is closed by the signal corresponding to minimum level.

IPC: G05F1/573
Filed: 1960-05-09
Abstract: 940,784. Automatic voltage control systems. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. May 8,1961 [May 9, 1960], No. 16250/60. Heading G3R. A D.C. voltage regulator circuit having input and output terminals 12,13 has its output voltage held constant by a series regulating transistor 11 whose conductivity is altered by a control transistor 15 biased by a potential divider 17, a Zener diode 18 providing a reference voltage. A second control transistor 16 protects the transistor 11 against overload and is normally inoperative when the volt drop across the portion of the divider 21 between the emitter of transistor 16 and the resistor 20 is greater than the volt drop across the resistor 20. When the output voltage falls slightly below its regulated level on reaching the current limit of transistor 11, the diode 18 ceases to conduct and the voltage on divider 21 is then derived from the divider formed by resistances 19, 22. Further fall in output voltage causes the volt drop between the emitter of transistor 16 and the resistor 20 to fall below that across the resistor 20, with the result that the output current is limited by the action of transistor 16 on transistor 11. To minimise current flow when the terminals 13 are short-circuited, the resistor 20 may be replaced by a non-linear element such as a rectifier poled forwardly. Transistor 11 may be replaced by a plurality of transistors arranged in parallel, series,or series-parallel relationship.

Abstract: 940,522. Reactor control rods. UNITED STATES ATOMIC ENERGY COMMISSION. April 30, 1962 [May 24, 1961], No.16355/62. Heading G6C. [Also in Division E2] A cruciform control rod 33 is joined to a cruciform follower 29 by means of a T-shaped extension 71, the cross-arms 75 of which fit into cut-out portions 77 of the follower. A pin 85 inserted where the cross-arms 75 meet has a cone-shaped bearing surface 86 mating with a complementary coneshaped recess 87 in the follower 29 so that the latter and the control rod 33 can be rotated relatively around their common axis 89. The arms 91 of the follower 29 have recesses 101 at their ends in which are mounted resilient C- shaped springs 109 with ends 111 having V-shaped keys 113 protruding from the tops of the recesses. When the follower 29 and control rod 33 are rotated in opposite directions about the axis 89, the keys 113 contact lead-in tapered portions of the control rod arms 95 which compress the springs 109 and force the keys 113 into grooves 115 in the arms 95, thus restraining the follower and control rod from relative opposite rotation. When the control rod has to be replaced, it is removed from the reactor together with the follower and the latter held in a support while the control rod is rotated around axis 89. This depresses the springs 109 into the recesses 101 and disengages the control rod arms 95 from the follower arms 91. The invention is described with particular reference to control rods for pressurised water reactors.
